Notes and Safety

Warning: Cut off all power of the inverter before installation! Wait for 5 minutes after power off. Danger of high voltage! Danger to life due to high voltage of this machine!

Introduction

Basic features

The DTSU666 CT Meter can achieve energy management together with SolaX three-phase inverters. It applies to 200A systems and below, measuring the import, export, and total power and energy.

System Diagram: A diagram shows a PV array connected to a SolaX inverter (INV), which is then connected to the Energy Meter (DTSU666-CT). The Energy Meter is also connected to the electrical grid and the LOAD.

Terminals and Dimension

Dimensions: The meter has dimensions of 100mm height, 72mm width, and 45mm depth. It features terminal blocks for various connections.

Terminal Layout: A diagram illustrates the terminal layout, showing connections for RS485 (ports 24, 25), Voltage wires (ports 2, 5, 8 for L, port 10 for N), and CT input ports (ports 1, 3, 4, 6, 7, 9).

Wiring Diagram: Detailed wiring diagrams are provided for both three-phase three-wire and three-phase four-wire systems, indicating connections for Grid, CT input, RS485, and Inverter.
